23 4 Driver installation 4.1 Overview This chapter describes how to install a single host machine with Fujitsu InfiniBand hardware installed. A server can be properly installed with all required InfiniBand drivers and software during Linux installation or afterwards by using the OpenFabrics Enterprise Distribution (OFED). In the first case, the correct packages must be selected during setup and should only be performed by an advanced user. For simple complete installation, use the OFED drivers. If you purchased the products from Fujitsu Japan, you can download it from The chapter includes the following sections: section "OFED installation" on page 24 section "Updating Firmware after Installation" on page 30 section "Subnet Manager" on page Software and hardware requirements Required Disk Space for Linux Installation 1 GB PCI Device ID 15B3:1013:15B3: B3:1013:15B3:0032 Operating system RHEL (Red Hat Enterprise Linux) 6.6, 6.7, 7.1 or higher SLES11 (SuSE Suse Linux Enterprise Server) SP3, SP4, SLES12 or higher InfiniBand HCA (100Gb) EDR User Manual 23

24 OFED installation Installer privileges The installation requires administrator privileges on the target machine. 4.3 OFED installation Please install OFED by the following steps after the OS installation by SVIM (Server Installation Manager). Ê Download OFED from Fujitsu Technology Solutions Web site Ê If you purchased the products from Fujitsu Japan, you download it from V CAUTION! This software is the driver package of ConnectX-4 IB HCA card (100Gb). This package driver does not support ConnectX-3 IB HCA card (56Gb). When OFED downloaded from the above is being used, please don't apply the RHEL native OFED at the time of RHEL update Installing Mellanox OFED The installation script, mlnxofedinstall, performs the following: Discovers the currently installed kernel Uninstalls any software stacks that are part of the standard operating system distribution or another vendor's commercial stack Installs the MLNX_OFED_LINUX binary RPMs (if they are available for the current kernel) Identifies the currently installed InfiniBand and Ethernet network adapters and automatically upgrades the firmware Usage./mnt/mlnxofedinstall OPTIONS 24 User Manual InfiniBand HCA (100Gb) EDR

25 OFED installation The installation script removes all previously installed Mellanox OFED packages and re-installs from scratch. You will be prompted to acknowledge the deletion of the old packages. I Pre-existing configuration files will be saved with the extension.conf.rpmsave. If you need to install Mellanox OFED on an entire (homogeneous) cluster, a common strategy is to mount the ISO image on one of the cluster nodes and then copy it to a shared file system such as NFS. To install on all the cluster nodes, use cluster-aware tools (such as pdsh). If your kernel version does not match with any of the offered pre-built RPMs, you can add your kernel version by using the mlnx_add_kernel_support.sh script located under the docs/ directory. I On Redhat and SLES distributions with errata kernel installed there is no need to use the mlnx_add_kernel_support.sh script. The regular installation can be performed and weak-updates mechanism will create symbolic links to the MLNX_OFED kernel modules. The mlnx_add_kernel_support.sh script can be executed directly from the mlnxofedinstall script. For further information, please see --add-kernel-support option. Example The following command will create a MLNX_OFED_LINUX ISO image for RedHat 6.3 under the /tmp directory. #./MLNX_OFED_LINUX-x.x-x-rhel6.3-x86_64/mlnx_add_kernel_support.sh -m /tmp/mlnx_ofed_linux-x.x-x-rhel6.3-x86_64/ --make-tgz Note: This program will create MLNX_OFED_LINUX TGZ for rhel6.3 under /tmp directory. All Mellanox, OEM, OFED, or Distribution IB packages will be removed. Do you want to continue?[y/n]:y See log file /tmp/mlnx_ofed_iso log Building OFED RPMs. Please wait... Removing OFED RPMs...
